The figure below shows the state chart of the discrete output function block.
State name Description
Available
This is the initial state after power on. The Device Block is
in Executing state (see section 7.2.1).
Idle
This state cuts the signal flow between the SetpointValue
of the certain Discrete Output function block instance and
its dedicated underlying actuation hardware. The behavior
is according the IdleActionSelector parameter.
Ready
The connection between the SetpointValue parameter of
the certain Discrete Output function block instance and its
dedicated underlying actuation hardware is recovered. The
instance is waiting for new SetpointValue parameter
values.
Run The instance is working in its dedicated way.
Recoverable Fault
There is a temporary fault. The reason is device and
manufacturer specific.
Unrecoverable
Fault
There is a fault with no automatic return. This fault can
force a Critical Fault according to section 7.2.1 or refers to
the certain instance only.
Executing
This state is defined in section 7.2.1, i.e. the state machine
is working in this device state only.
